Page 10: Controls And Functions
2. Level Controls The Level Controls on the CV Series amplifiers utilize a DC voltage to control the output level of the CV Series amplifiers through a VCA (voltage controlled amplifier). The knobs can be removed and replaced with black plastic caps provided with the amplifier. -
Page 11: Power Switch
The digits preceding the last digit designate the rated output power of a channel or zone for that amplifier. The CV Series amplifiers are a constant voltage design, and have the same output at 4 ohm, 8 ohm, 25V, 35V, 50V, 70V and 100V taps. Thus a CV1502 has two channels or zones each rated at 150 watts per channel at any selected tap. -

The Serial Number is used by Carver Professional to track units and establish their warranty status. Be sure to record the serial number of all Carver Professional units, and to keep those records in a safe and secure location for future reference. Never remove the serial number, as this will void the warranty. -

(Note: The signal at the Send Pins of the Effects Loop are post any signal processing performed by a optional input module that may be in use in the CV Series amplifier). Connections to the Effects Loop are intended to be local, and signals sent over long wire runs are not recommended. -
Page 15: Thermal Considerations
A minimum space of 1U should be left between CV Series amplifiers at no more than a 12U interval. This should allow sufficient cooling of the amplifiers. If the CV Series amplifiers are mixed with other devices, caution should be taken to locate the CV Series amplifiers together, facilitating the chimney effect of their heatsink design. -
Page 16: Input Sensitivity
Another input to the CV Series amplifiers is provided via the EFX Loop’s RCV (receive) input. This input is only available when the FX Loop is enabled on the DIP switch located on the rear of the amplifier. This input is designed for unbalanced line level input only, and should only be used with equipment that is local to the CV amplifier or rack containing the CV amplifier, such as, an outboard signal processing device or the SND output from the FX Loop on the same or another (local) CV amplifier. -

500 watts. (See Figure 8) It is also necessary to connect the commons together when bridging a distributed load. Caution: A 4 ohm mono load should not be connected to the CV Series amplifier in the bridged mode, but you can use the parallel mono configuration with a 4 ohm load. -
Page 18: Power Sequencing
Important Note: When bridging the CV Series amplifier at one of the distributed voltage outputs, it is necessary to connect the Common connections for the distributed voltages together. The commons on the secondary side of the output transformers are floating. This is not true for the low-impedance outputs. -
Page 19: Ground Test Procedure
0.2 ohms we recommend that you connect the chassis ground terminals of the sequence connector together in a daisy chain as in Figure 12. Repeat this for each CV Series amplifier in the rack. If there is less than a 0.2 ohm resistance from the rail to the chassis ground of each unit you do not have to daisy chain the chassis grounds together. -

Using Other Amplifiers in the Power Sequence The Carver pm700, pm950, pm1400, pt1800 and pt 2400 can be use together with the CV Series amplifiers in a “Sequenced” configuration.

This may be useful if one desires a visual indication that the CV Series amplifier is powered ON. The +5V at the “Remote Level”...

A/V Systems. A voltage ramp provided by one of these manufacturers, and controlled by their system can be used to adjust level on the CV Series amplifiers. Apply a control voltage from the external source of the desired control system to the “Remote Level” input terminal. This voltage may be applied to either or both of the CV1 and CV2 input terminals. -

ARE AND Care: Wipe off the CV Series Amplifier’s front panel and chassis from time to time, with a soft, dry cloth. If you have something stubborn to remove, use a mild dish soap or detergent sparingly applied to a soft cloth. - Page 25 Email: carverpro@phoenixgold.com Email: carverpro@phoenixgold.com Carver Professional reserves the right to improve its products at any time.

Page 27: Appendix B
Appendix “B” Input Sensitivity Jumpers 101 and 102 on the standard input module’s PCB are used to set the Input Sensitivity of the amplifier for each channel or zone. The output level of the input source determines the setting. Since, each channel or zone may have a different input source, it is acceptable to have these jumpers set differently according to the potential output level of the input source.
